I'm a fan of vaccines because I'm a fan of facts. And the facts show vaccines are a safe and proven way to stop people suffering and dying from preventable diseases.
Even then, I wouldn't care about people leaving themselves open to these diseases if it was only about them. But there are people who can't be vaccinated, like the very young, very old, or people who have allergies.
If one of these people catches a disease like mumps, it's serious. Mumps leads to meningitis in one in 10 cases.
Or maybe measles. There have been several New Zealand outbreaks of this disease over the past few years, thanks partly to those who refuse vaccinations.
Measles can cause pneumonia, deafness, brain swelling and death.
People who can't be vaccinated rely on the rest of us being getting the jab so they don't die from a totally preventable disease. They don't have a choice.
You don't have the freedom to speed in your car, or drive while you're drunk, because you might hurt other people.
Choosing not to be vaccinated is the same unacceptable risk.
To help clear up the many myths out there, I called Dr Helen Petousis-Harris, director of research at the Immunisation Advisory Centre, and senior lecturer at Auckland University.
We talked about the misinformation that's out there, the truth behind it, and why there are serious consequences for people choosing not to be vaccinated.
